Lets note that there is no context with the line where it supposedly says "vergils child". Lets also note that artbooks contain unused/scrapped/discarded plots/designs/tidbits. Also the character encyclopedia was released long after that art book. Dante is 10 years older since no new info has been presented to state otherwise. That doesnt mean that Nero couldnt have been cloned at some earlier point in time. Quick side note since Dante and Vergil are twins they have matching genetics, which would mean Nero is his clone too. Obviously somethin was done differently since he isnt half demon. He could have been made Sephiroth/Angeal/Genesis style. Or like the second Greed from FMAB. I have to disagree about him being Vergils heir though. Hes more like Sparda himself than anyone else. Dante is 29-30 by DMC4 we dont have dates but we have the time-lapses
